Several kinds of techniques are under development for effective correction of a tropospheric
phase fluctuation in millimeter-and submillimeter-wave radio interferometry, including very …

An experiment for compensating interferometer phase fluctuations due to the turbulent
troposphere was conducted with the paired antennas method (PAM) using different sky …

We review millimeter interferometric phase variations caused by variations in the
precipitable water vapor content of the troposphere, and we discuss techniques proposed to …

High‐accuracy measurements made by using very long baseline interferometry require
corrections for the effects of the atmosphere. A ray‐tracing analysis shows that the phase …

Signal-to-noise ratio (SNR) in very long baseline interferometry (VLBI) is reviewed. A VLBI
observation is first summarized from the viewpoint of signal processing, and the SNR of one …

Over the past several years the millimeter wave VLBI (Very Long Baseline Interferometry)
observations have been intensively performed. However phase fluctuation due to …

An accurate real-time VLBI (Very Long Baseline Interferometry) system with 47 km baseline
connected by a terrestrial microwave link was developped. Using the system three kinds of …

Using multiple-receiver arrays, the techniques of spaced antennas and spatial domain
interferometry have been widely utilized in mesosphere-stratosphere-troposphere (MST) …

Very long baseline interferometry (VLBI) experiments at a frequency of 89 GHz (3.4‐mm
wavelength) using hydrogen maser frequency standards show that under good atmospheric …

The balloon-borne very long baseline interferometry (VLBI) experiment is a technical
feasibility study for performing radio interferometry in the stratosphere. The flight model has …
